b. 240

composition: (Op. 4), Sonata in C minor, Mvt I

..

The deletions visible in A at the beginning of the bar reveal that Chopin initially wrote d1 as the bottom note of the 1st chord, accompanied by F (con 8) as the L.H. octave. Therefore, the  to the next d1 crotchet was most probably meant to cancel the alteration and not to perform the role of a cautionary accidental following d in the preceding bar.

In A Chopin overlooked the flats restoring b1 in bar 245 and b2 in bar 246. The patent oversight was already noticed by GE (→FE,EE,IE), yet flats were added only in bar 246 (to the penultimate R.H. and L.H. octaves).
